XenServer 6.0 includes enhancements to simplify management, improve performance and scale, and integrate additional high availability and disaster recovery capabilities. Key features include integrated StorageLink for storage management, workload balancing via a virtual appliance, vApps for controlling VM startup order in HA and DR scenarios, and support for Microsoft SCVMM and SCOM. GPU pass-through and IntelliCache are optimized for XenDesktop deployments.

- 53. GPU Pass-through: Howdoes it work • Identical GPUs in a host auto-create a GPU group • The GPU Group can be assigned to set of VMs – each VM will attach to a GPU at VM boottime • When all GPUs in a group are in use, additional VMs requiring GPUs will not start • GPU and non-GPU VMs can (and should) be mixed on a host • GPU groups are recognized within a pool • If Server 1, 2, 3 each have GPU type 1, then VMs requiring GPU type 1 can be started on any of those servers
